How Do Insurance Companies Determine Risk?

Insurance companies generate revenue by accepting financial risk in exchange for premium payments, using statistical principles such as law of large numbers and risk pooling to limit losses and minimize their exposure.

Insurance carriers evaluate applicant data such as age, location and risk history to establish premium rates. They often rely on advanced techniques like actuarial science and catastrophe modeling.


Insurance companies take on risks in order to provide customers with coverage. While the hope is they won’t need to make payments out, unexpected events do happen and when that occurs they must find ways to cover it financially. That is why insurance providers must carefully select who they cover and set premium charges accordingly; also they need to actively watch out for fraud, decline suspicious risks and focus on prevention as a strategy to minimize losses and keep premium costs affordable.

Underwriting is the process that insurers use to assess and evaluate prospective policyholders. This practice is integral for all types of insurance – be it property casualty, life or health policies. Insurance companies employ actuaries with incredible mathematical ability who collect data to calculate rates – they take into account factors like accidents, fires, car thefts and property damages when developing this rating system.

When applying for insurance, an underwriter will carefully consider all of this data to assess if you qualify as a candidate for coverage. They’ll consider factors like your age, health and credit history in addition to the kind of policy you want – in some cases they may even require that you undergo a medical examination first before being accepted for coverage.

Example: If you live in an area prone to flooding and are applying for home insurance, the underwriter will consider past flood history, your type of building and proximity to water sources when assigning a value that takes into account flood risks for your house – this helps determine how much premium they’ll charge you.

Underwriting is an integral component of insurance, yet it can be challenging to predict an individual or business’s risk accurately, due to uncontrollable factors that impact risk of loss. Therefore, it is crucial that underwriters regularly refine and improve the process in order to make it as accurate as possible.


Insurance policies allow people to make financial claims when damage occurs, with premiums paying as compensation in exchange. Insurers assess risk and set prices accordingly by calculating the likelihood that policyholders will file claims; this process is called underwriting. Insurance professionals collect various data during underwriting – much of it considered nonpublic – such as health, age, lifestyle and driving records in order to classify individuals into different risk classes; those belonging to higher risk classes will pay higher premiums than those in lower risk groups.

Insurance companies rely on accurate risk evaluation in order to provide customers with adequate coverage, and set accurate pricing structures so they can cover claims without going bankrupt. Outside factors can wreak havoc with their businesses by altering economic conditions, natural disasters or regulatory changes; so their goal should be to mitigate such risks as they arise in order to stay ahead of the game in an ever-evolving marketplace.

Insurance providers estimate expected losses from products or portfolios using actuarial science and mortality and morbidity tables, to predict when losses might occur and their severity. It’s therefore vital that insurers invest in assets to cover future liabilities.

Risk management strategies can help mitigate investment risks. Implementing such an approach allows insurance companies to better control risks and safeguard profitability.

Insurance is an integral component of modern society; without it, many aspects of our daily lives would simply not exist – perhaps modern civilization would cease to exist altogether without it! But exactly how do insurance companies assess risk, and provide adequate protection to their policyholders?

Risk Assessment

Risk evaluation is at the core of insurance underwriting. This involves evaluating various factors to ascertain the level of risk associated with individuals, businesses or assets in order to make informed decisions regarding pricing, coverage and risk management strategies. Risk evaluation plays a pivotal role in providing companies with protection against financial loss while offering customers quality service.

Process of Risk Evaluation. Risk evaluation can take many forms: informal social assessment; such as assessing economic and household risks; to a more formal and structured corporate process. Assessment involves combining probability with consequences in order to create an overall estimate of risk – this calculation enables insurers to balance both risk and profitability when making their underwriting decisions.

Underwriting can be an intricate and time-consuming process. To accurately assess potential risks, underwriters must review many different factors, including past claims data and loss history, product characteristics such as mortality risk or damage risks and theft risks for each product – thus different policies carry different degrees of risk that must be priced accordingly.

Underwriters assess applicants and their risk profiles in addition to reviewing past losses. This evaluation process involves taking many factors such as age, location and risk management history into account when making their determination for appropriate coverage and deductible amounts on each policy; additionally they identify high-risk insureds and create strategies to mitigate their risk.

Risk analysis’s primary aim is identifying hazards. This involves estimating their likelihood and severity – it is an absolute legal requirement that businesses conduct and keep up-to-date a risk evaluation program.

Surveys, inspections and observations are the three most prevalent ways of hazard identification; however, other methodologies like artificial intelligence-based image processing software have become increasingly popular as an effective means of consistently evaluating properties and creating more accurate valuations with less likelihood for human error to skew valuations inaccurately or misleadingly.

Catastrophe Modeling

Insurance companies need to accurately evaluate risk and its cost in order to establish an appropriate premium, which can be a complex and time-consuming process. One effective approach for gathering this data is through catastrophe modeling, which quantifies potential risks by using data regarding properties’ locations, physical characteristics of structures and coverages with mathematical models to calculate losses – this allows insurers to estimate how much cash reserve money they must set aside in case claims arise due to particular risks.

Catastrophe modeling is an in-depth computer-assisted calculation that integrates multiple disciplines, including actuarial science, engineering, meteorology and seismology. It serves as an excellent means for studying drivers of risk at an intimate level even when previous experience may not exist or is limited or unavailable.

An insurance catastrophe model includes three key elements: hazard, vulnerability and exposure. A hazard model represents events mathematically while vulnerability and exposure models follow the concept of the “Risk Triangle.” Insurance companies use catastrophe models not only for natural disaster risk assessment purposes but also use them to assess other events that may arise such as terrorist acts.

AIR and Praedicat have come together to host a series of webinars focused on casualty catastrophe emerging risk landscape, modeling and action. Hosted by the NAIC Center of Insurance Policy and Research (CIPR), these events provide regulators with technical expertise, tools, and information needed to effectively regulate their markets.

As insurance continues to experience new forms of volatility, transparent and customizable catastrophe models become ever more critical for an accurate representation of risk. CoreLogic’s ELEMENTS catastrophe modeling platform gives users access to tools for developing a custom view of risk; including customizing and adjusting hazard and vulnerability model components as well as an open financial loss calculation engine and quantify uncertainty definition and quantification capabilities.
